Prepare your PEB visit
The better documented the certifier is, the better your PEB score will be. Without proof, the certifier must use default values, which are often more penalizing.
Document checklist to prepare
Insulation works
If insulation works were done, prepare photos of the work (showing the insulation thickness) and detailed original invoices mentioning the site address, insulation type and thickness.
Windows and frames
Prepare the window frame installation invoice to obtain the U insulation coefficient.
Property plans
If you have property plans, send them to us before the visit. This makes the certifier's job easier.
Room accessibility
The certifier must have access to all rooms. In apartments with collective heating, make sure the cellar or technical room is open. If the insulation is visible through an access hatch, make sure it is accessible.
Heating and installations
Prepare the technical sheet or installation manual of your boiler, as well as the periodic inspection certificates.
Don't throw anything away! Even an old technical brochure from a 1995 window can be worth a few more points than an arbitrary default value.
